PowerDale is a small town with around 100 residents. Most houses have a smart meter installed that can save and send information about how much energy a house has consumed. Each household needs to sign up with one of the available power suppliers, and choose a pricing plan offered by them. The household energy consumption is then charged based on the selected pricing plan.
JOI Energy is a new start-up in the energy industry. Rather than selling energy, they want to differentiate themselves from the market by recording their customers' energy usage from their smart meters and recommending the best supplier to meet their needs.
This codebase currently implements the logic for storing and fetching energy consumption readings from a smart meter, as well as the logic to recommend the cheapest price plan for a particular household's energy consumption patterns.
There are three major power suppliers in town, each with their own pricing plans:
- Dr Evil's Dark Energy
- The Green Eco
- Power for Everyone
To trial the new JOI software 5 residents have agreed to test the service and share their energy data.
